DESCRIPTION OF THE PREFERRED EMBODIMENTS In the illustrated example, a tank 1 is a lower tank 1.
It is composed of a front plate 14, a rear plate 15, both side plates 12 and 12, a bottom plate 6 and the like, which are composed of a and an upper tank 1b, and are appropriately frame-reinforced by columns or the like. Upper frame 19 of lower tank 1a
The lower frame 20 of the upper tank 1b is detachably provided by bolts or the like. When adjusting the tank capacity,
An intermediate tank is interposed between the upper and lower tanks 1a and 1b by the same means. Agitating shafts 3, 3 are rotatably mounted between the front and rear plates 14, 15 on the left and right sides of the lower tank 1a. A plurality of mounting brackets 21, around the stirring shaft 3,
21 is welded over substantially the entire length, and the bracket 2
The stirring claws 2, 2 are fitted into the parts 1, 21 and bolted.
The stirring claw 2 has a shape like a plowing blade, that is, a thick and thin flat plate-like material is fitted into and attached to the brackets 21 and 21, and the mounting portion 2a having a predetermined height is sequentially rotated in the rearward direction. A claw portion 2b is formed which is bent backward toward the front side, and the leading end portion is further bent toward the transport direction A side to form a feed surface 2c. Further, the front edges in the rotational direction are formed at an acute angle and are provided with a blade portion 2d. The stirring claws 2, 2 of the left and right stirring shafts 3, 3
Are both inwardly rotated, and the rotation direction is such that the right side rotates left when viewed from the front and the left side rotates right. However, since the conveying direction is the same direction A, A, the left and right stirring claws 2, 2 Is symmetrically configured. Further, the stirring claws 2, 2 are the stirring shafts 3.
By sequentially changing the phase every 90 degrees from the starting end side and attaching in a spiral shape, the compost raw material can be conveyed in the direction of arrow A while stirring. In addition, two stirring claws 2, 2 are provided in the same phase position near the front plate 14 to quickly convey the compost raw material on the front plate 14 side to reduce the load. In addition, the end surface of the agitation shaft 3, that is, several agitation claws in the vicinity of the rear plate 15 are formed by bending the feed surface 2c to the opposite side to form the reverse feed agitation claws 2E, 2E, and can be conveyed in the direction opposite to arrow A. Configured. Therefore,
The compost raw material fed back in the direction opposite to the arrow A by the feeding surface 2c is stirred up with the compost raw material fed in the direction of arrow A by the stirring claws 2, 2 and is spouted upward and sent out to the central side. For this reason, the pressure is not excessively fed to the rear plate 15 side, and the load can be reduced. The transport shaft 5 is
Located in the lower center of the lower tank 1a, the front and rear plates 14,1
5 is rotatably mounted in the direction of arrow B, and a plurality of transport blades 4, 4 are provided around the transport shaft 5 along the entire length thereof.
The base is welded. The carrier blade 4 is made of a flat plate and has a feeding action in the direction of arrow B by inclining the base portion and welding it around the carrier shaft 5, and a plurality of carrier blades 4, 4 are arranged around the carrier shaft 5. It is configured so that it can be conveyed in the direction of arrow B by sequentially changing the phase every 90 degrees and attaching the spiral shape. In addition, in order to increase the transporting force of the transporting blade 4, it is preferable that the upper surface of the scooping be bent and formed. In addition, since there is only one transport shaft 5 and the constitution is such that the compost raw material is taken over from the ends of the two left and right stirring shafts 3, 3 that transport in the direction of arrow A and is circulated and transported in the direction of arrow B, the transport amount is balanced. In order to do so, the blade surface of the conveying blade 4 is made larger than that of the stirring claws 2, 2 and the mounting inclination angle is made large.

The bottom plate 6 of the lower tank 1a at the end of the transport shaft 5 has a shutter 2 at a fixed interval from the front plate 14 side.
A discharge port 7 that can be opened and closed by 2 is provided. The discharge port 7
The transport shaft 5 between the front plate 14 and the front plate 14 is provided with several reverse feed transport blades 4A, 4A that can be reversed and reversely fed to the other transport blades 4 to compost to the front plate 14 side at the time of stirring. It prevents the pressure contact of the raw materials and enhances the discharge efficiency during discharge. Furthermore,
A narrow trapezoidal plate-shaped feed-up blade 8 is attached to the transport shaft 5 located near the center of the discharge port 7, and the compost raw material transported in the direction of arrow B by the transport blades 4, 4 is moved upward. It is configured to be fed up and taken over by the left and right stirring claws 2, 2 for circulation. When the front and rear of the tank 1 are long, the rear plate 1
